COMBINED SUGAR-CANE CUTT ER AND CRUSHER.

SPECIFICATION forming part of Letters Patent No. 430,806, dated June 24, 1890.

Application filed March 26, 1888. $erial No. 268,481, (No model.)

struction of the combined sugar-cane cutter and crusher, all as hereinafter described and claimed.

Reference is to be had to the accompanying drawings,forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures. 15

Figure 1 is a central section of my invention. Fig. 2 is an enlarged sectional plan View on the line y y of Fig. 1. Fig. 3 is a Fig. 4 is a plan View of the ring I) detached. Fig. 5 is an enlarged plan view of the crushingcone. Fig. 6 is an enlarged sectional elevation of the shell, showing the cone in position and partly broken away; and Fig. 7 is a detail sectional view of the'crushing-cone on the line z .2, Fig. 5.

A represents the crushing'cone, and B the shell surrounding the same, each spirally grooved to crush and grind the cane. Upon the shell B is mounted the sleeve or cylindrical casing C, which is cut away or otherwise formed at its lower inner edge a to form a space a at the juncture of the casing with the shell B. 'Within the casing O is fitted the ring 12, and above this is fitted the hopper-sleeve D, formed with the inner tube D and radial partitions D which form quadrant spaces, into which the cane to be cut and crushed is fed, the partitions D serving to retain the cane while being out by the knife E, which is revolved by the drive-shaft F, on which the grinding-cone A is secured.

The knife E is scroll-shaped, and is, by preference, formed with the teeth e, like sawteeth, at its edge, and beneath it upon the shaft F is secured the plate G, which supports the cane while the knife E cuts it. An openin g G is formed through the plate G, beneath the knife E, for the short pieces of cane to drop through to the crushing-cone and shell below. The short-cut pieces of cane also find their way from the plate G to the mill through the above-mentioned space a, formed in coincidence with the periphery of the plate G.

The ring I) (see Figs. 1 and 4) is cut away to form the narrow channel I), which constitutes a space or clearance for the outer edge or teeth of the knife E, so that the stalks of cane will be cut entirely through, and so that there will be no clogging of the machine; and said ring is connected to the hub 12 by the radial spokes b so that the knife E runs between the lower ends of the radial partitions D and the said radial spokes b so that the cane being cut will be held or retained both above and below the knife. The ring I) is locked to the lower edge of the sleeve D, and held stationary by means of a notch n in the ring and a projection 11. at the bottom of the sleeve D. lower end of the tube J, which fits upon a square portion of the shaft F, as shown in Figs. 2 and 3.

The knife'E is made fast to the tube J by the tube J, which turns within the hub D of the hopper-sleeve D, which latter is made fast to the casing C by the set-screws f, and the tube J is held fast upon the knife by the cap-nut g, applied to the upper end of the inner tubeJ, as shown clearly in Fig. 1. A short sleeve j comes between the plate Gand knife E. The sleeve D and easing 0 act as one part and might be permanently fastened together by the screws f, or otherwise.

The above details of construction may be varied, the sole object being to secure in a practical way the knife E and plate G to the shaft F, and to hold the radial partitions D stationary, so that the knife will effect a clean cut of the cane against each partition.

The cone A is formed with spiral flanges A, preferably three in number, which act as oonveyers to the short pieces of cane, to transfer them with sufficient rapidity from the top of the cone down to the principal crushing-surface near and at the lower edge of the cone. The said flanges are of considerable projection at the top, but vanish gradually flush with the main crushing corrugations A A of the cone. The surfaces a of the ribs A, facing the direction of motion of the cone, are made fiat, while the outer surfaces a are rounded, as shown clearly in The plate G is secured to the Fig. 5. The lower edge of the cone is formed with short corrugations a; The concave surfaces a forming the principal corrugations A are made abrupt or of short radius at a, as shown in Fig. 7, to form sharp shoulders or edges a and from the bottom of this short abrupt curve the said surfaces are struck from a radius of considerable length.

The shell B is formed with corrugations B, extending to the lower edge of the shell, and also with the short corrugations b at its lower edge, as shown clearly in Fig. 6. To avoid breakage in case any solid foreign substance should enter the crusher, the lower end of the shaft F is stepped in a separate socket or cup M, held loosely in a stand or base N, in which are pivoted the weighted levers O, the upturned points m of which support the socket M, shaft, and cone A. The said shaft F is loose in the sleeve or tube J, so that the shaft may have longitudinal movement. The socket M is attached to the base N by the rods m, provided with limit-nuts m by which the space between the adjacent grinding-surfaces of the cone A and shell B may be increased or diminished, as desired.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The shell 13, corrugated upon its inner surface, the casing 0 above the same, and the sleeve D, having the radial partitions D in combination with the knife E, apertured plate G, radial arms b below the knife, and the crushing-cone A, all arranged to operate substantially as described.

2. The crushing-cone A, shell 13, the casing C, and the ring I), cut away to form the chanthe knife projecting at right angles therefrom just below the partitions D the tube J, surrounding the tube J above the knife, the short tube j on the tube J below the knife, the radial arms or spokes 17 below the knife, the apertured plate G on the lower end of tube J, the operating-shaft connected to the tube J, and a nut screwed upon the upper end of the tube J, clamping the knife and plate G firmly in place, substantially as set forth.

4. A combined cutting and crushing machine comprising a hopper, a cylinder provided with radial partitions communicating at its upper end therewith, and a grindingshell registering with the lower end of the cylinder, a rotary centrally-apertured knifecarrying tube or sleeve supported vertically in said cylinder and provided with a central vertical squared aperture or bore, the knife 1 carried by said tube, a vertical shaft having a squared upper end entering said bore to slide therein and rotate the sleeve or tube, a grinding-cone secured on the shaft within the shell, and a downwardly-yielding step or socket supporting the lower end of the shaft.
